Metzincins are key molecules in the degradation of the extracellular matrix and play an important role in cellular processes such as cell migration, adhesion, and cell fusion of malignant tumors, including cutaneous melanoma (CM). We hypothesized that genetic variants of the metzincin metallopeptidase family genes would be associated with CM-specific survival (CMSS). To test this hypothesis, we first performed Cox proportional hazards regression analysis to evaluate the associations between genetic variants of 75 metzincin metallopeptidase family genes and CMSS using the dataset from the genome-wide association study (GWAS) from The University of Texas MD Anderson cancer Center (MDACC) which included 858 non-Hispanic white patients with CM, and then validated in the dataset from the Harvard GWAS study which had 409 non-Hispanic white patients with invasive CM...

BACKGROUND: Deficits in social cognition may be among the most profound and disabling sequelae of paediatric traumatic brain injury (TBI); however, the neuroanatomical correlates of longitudinal outcomes in this domain remain unexplored. This study aimed to characterize social cognitive outcomes longitudinally after paediatric TBI, and to evaluate the use of sub-acute diffusion tensor imaging (DTI) to predict these outcomes. METHODS: The sample included 52 children with mild complex-severe TBI who were assessed on cognitive theory of mind (ToM), pragmatic language and affective ToM at 6- and 24-months post-injury...

Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of non-Hodgkin lymphoma. Although 5-year survival rates in the first-line setting range from 60% to 70%, up to 50% of patients become refractory to or relapse after treatment. Published analyses of large-scale outcome data from patients with refractory DLBCL are limited. The international, multicohort retrospective non-Hodgkin lymphomaresearch (SCHOLAR-1) study retrospectively evaluated outcomes in patients with refractory DLBCL, which, for this study, was defined as progressive disease or stable disease as best response at any point during chemotherapy (>4 cycles of first-line or 2 cycles of later-line therapy) or relapsed ≤12 months of autologous stem cell transplantation...

PURPOSE: Recent developments in electronic technology are making it possible to home monitor the sensitivity of the central visual field using portable devices. We used simulations to investigate whether the higher test frequency afforded by home monitoring improves the early detection of rapid visual field loss in glaucoma and how any benefits might be affected by imperfect compliance or increased variability in the home-monitoring test. DESIGN: Computer simulation, with parameter selection confirmed with a cohort study...

INTRODUCTION: Prostate biopsies following localized radiation therapy for prostate cancer often demonstrate residual prostatic carcinoma with treatment effect (CTE). The final oncological outcome of prostatic CTE is currently uncertain. We studied the pathological and oncological outcomes for a large cohort of patients who had CTE on post-radiation therapy biopsy and subsequently underwent salvage radical prostatectomy (SRP). METHODS: A single-centre retrospective review of all SRPs performed from 1995-2014 was performed...

This White Paper, prepared by members of the Cardiac Safety Research Consortium, discusses important issues regarding sudden cardiac death in the young (SCDY), a problem that does not discriminate by gender, race, ethnicity, education, socioeconomic level, or athletic status. The occurrence of SCDY has devastating impact on families and communities. Sudden cardiac death in the young is a matter of national and international public health, and its prevention has generated deep interest from multiple stakeholders, including families who have lost children, advocacy groups, academicians, regulators, and the medical industry...

The Pisum arvense lectin (PAL), a legume protein belonging to the Vicieae tribe, is capable of specific recognition of mannose, glucose and its derivatives without altering its structure. In this work, the three-dimensional structure of PAL was determined by X-ray crystallography and studied in detail by a combination of molecular docking and molecular dynamics (MD). Crystals belonging to monoclinic space group P21 were grown by the vapor diffusion method at 293 K. The structure was solved at 2.16 Å and was similar to that of other Vicieae lectins...

Silver is known to possess anti-microbial properties that are of chemical origin. It is believed that either Ag atoms bind to thiol groups in bacterial enzymes or Ag(+) ions enter bacterial cells and denature the DNA molecule to kill bacteria. Silver nanorods, however, may kill bacteria by another mechanism: it is possible that the sharp tips of the nanorods puncture bacterial cells and kill bacteria via impalement-a physical mechanism. To test if this can indeed happen, we have compared the anti-microbial properties of silver and CdS nanorods...

Advanced practice providers (APPs) are increasingly being used in a variety of healthcare settings to provide care, treatment, and services to patients with cancer. They are also being deployed to acute oncologic settings to enhance patient care delivery and address the ever-evolving needs of patients in academic medicine. In response, the University of Texas MD Anderson Cancer Center developed a series of innovative clinical programs staffed by acute care APPs. These provide an opportunity to rapidly adapt to the acute care needs of patients with cancer while fostering the professional development of APPs within the full scope of their oncologic clinical practice...

PURPOSE: To determine dosimetric parameters associated with osteoradionecrosis (ORN) in oropharyngeal cancer (OPC) patients in the IMRT era. MATERIAL AND METHODS: Subsequent to institutional review board approval, we identified ORN in OPC patients treated with IMRT from 2002 to 2013. 1:2 case-control matching was implemented. Mandibular dose-volume histograms (DVH) were extracted. Dosimetric parameters were compared using non-parametric stats. Recursive partitioning analysis (RPA) was done to identify DVH correlates of ORN...

The standard approach of performing a completion axillary lymph node dissection (cALND) after a positive sentinel node for breast cancer patients is no longer generally accepted. This study applied the criterion of a 27% risk of having residual positive lymph nodes calculated by the MD Anderson nomogram to perform a cALND. This 27% cut-off is based on the number of positive non-sentinels in the Z0011 trial. A cohort of 166 cN0, sentinel positive breast cancer patients was used to validate the MD Anderson nomogram...

BACKGROUND CONTEXT: Neoplastic spinal instability is movement-related pain or neurologic compromise under physiologic loads with the Spinal Instability Neoplastic Score (SINS) developed to facilitate diagnosis. There is a paucity of evidence that mechanical instability correlates with patient-reported symptoms and that surgical stabilization significantly improves these patient-reported outcomes (PROs). PURPOSE: The objective of this study was to determine if SINS correlates with patient-reported preoperative pain and disability, and if surgical stabilization significantly improves PRO...

The NADPH oxidases (NOXs) play a recognized role in the development and progression of inflammation-associated disorders, as well as cancer. To date, several NOX inhibitors have been developed, through either high throughput screening or targeted disruption of NOX interaction partners, although only a few have reached clinical trials. To improve the efficacy and bioavailability of the iodonium class NOX inhibitor diphenylene iodonium (DPI), we synthesized 36 analogs of DPI, focusing on improved solubility and functionalization...

Treatment response and survival after bevacizumab failure remains poor in patients with glioblastoma. Several recent publications examining glioblastoma patients treated with bevacizumab have described specific radiographic patterns of disease progression as correlating with outcome. This study aims to scrutinize these previously reported radiographic prognostic models in an independent data set to inspect their reproducibility and potential for clinical utility. Sixty four patients treated at MD Anderson matched predetermined inclusion criteria...

Importance: We previously demonstrated that a major pathologic response to preoperative therapy, defined histopathologically by the presence of less than 5% viable cancer cells in the surgical specimen, is an important prognostic factor for patients with pancreatic ductal adenocarcinoma. However, to our knowledge, the patients most likely to experience a significant response to therapy are undefined. Objective: To identify clinical factors associated with major pathologic response in a large cohort of patients who underwent preoperative therapy and pancreatectomy for pancreatic ductal adenocarcinoma...

Invasive fungal infection (IFI) is a leading cause of morbidity and mortality in immunocompromised cancer patients. New triazole-based antifungal agents have been recommended for IFI prophylaxis in these patients. This retrospective study compared the safety and efficacy of voriconazole and posaconazole as prophylaxis in patients with hematological malignancies (HM), who were admitted to The University of Texas MD Anderson Cancer Center between January 2014 and August 2015, and who were started on single antifungal prophylaxis consisting of either voriconazole or posaconazole...
